The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

Getting the best possible performance out of your motion system is important. A poorly tuned regulator can result in wasted energy, wasted material or an unstable system. It is important that speed ...

We are now on the eight part of a ten part series about teaching your PI controller to behave like you want it to. At the heart of this discussion is a proposed tuning technique which allows you to be ...

A high accuracy, multi-axis wafer inspection stage, based on linear motors, air bearings, and piezo nanopositioning combining stages and motors providing high-speed motion and dynamic leveling and ...

A plan to temporarily get the milling machine going, by hooking up an external speed controller, has turned into a semi-permanent solution. I ordered a ‘DC-51’ speed controller – an enclosed ...

6-DOF motion, ultra-compact footprint, and high-speed photonics alignment algorithms integrated directly into the controller firmware. PI’s next-generation 6-axis automated alignment system for ...
